Abstract

Molecular ferroelectric HDA-BiI₅ has been utilized as the light-absorbing layer for organic–inorganic hybrid solar cells. Impressive polarization-induced enhancement of photoelectric performance has been achieved in the HDA-BiI₅-based solar device with a fast response time (∼0.64 ms). This work may provide new perspectives for molecular ferroelectrics in photovoltaic and photodetector applications.
